摘要
With the rapid increase of efficiency up to 23% during the past few years, hybrid organic-inorganic metal halide perovskite solar cells (PSCs) have become a research "hot spot" for many solar cell researchers. Hybrid perovskite structures have been obtained from methylammonuim lead bromide solutions deposited by one step spin coating deposition method. In this work, the effects of annealing temperature of the MAPbBr(3) films and devices have been investigated in details. By tuning the variation of the temperature, the properties including photoluminescence, crystallinity and morphology of perovskite films together with device performance have been affected significantly by the annealing temperature. The devices annealed with 70 degrees C shows the best device performance and exhibit a maximum Fill Factor around 76.5 and a maximum efficiency at 2.89%. (C) 2019 Elsevier B.V. All rights reserved.
